.04%. Yeah, you've had a couple, you're feelin' pretty good, feel like talking to everyone, relaxed, chillin'. Your speech might start to slur a bit, but you can still walk straight, talk normally, all that shit. W00t! Yeah! Beer!

.05%. Your muscular coodrination is a bit shaky. You amy stagger, but not obviously or anythin. Jokes will seem a kot funnier, and the fameous beer googgle eff fect will start to kick in.
